**The Program in C that uses a function power that calculates the power of a given numbe**r** is given below**:

```
Enter the base number: 7
Enter the exponent: 9
7.000000 raised to the power of 9 is: 40353607.000000
#include <stdio.h>
double power(double base, int exponent) {
double result = 1;
for (int i = 0; i < exponent; i++) {
result *= base;
}
return result;
}
int main() {
double base;
int exponent;
printf("Enter the base number: ");
scanf("%lf", &base);
printf("Enter the exponent: ");
scanf("%d", &exponent);
printf("%lf raised to the power of %d is: %lf\n", base, exponent, power(base, exponent));
return 0;
}
```

## Output:

Enter the base number: 7

Enter the exponent: 9

7.000000 raised to the power of 9 is: 40353607.000000

## Pro-Tips**💡**

In this program, the `power()`

function takes two arguments: a base number and an exponent.

It uses a for loop to calculate the power by iterating from 0 to the given exponent, multiplying the base number with the result each time.

In the main function, the program prompts the user to enter a base number and an exponent and then passes these values to the `power()`

function.

The function returns the power of the given number, and the program prints the result on the screen.

Please note that if the exponent is negative, the result would be a fraction, in that case you need to include the math.h library and use `pow()`

function which handles negative exponents and floating point bases.
